DETAILED DESCRIPTION OF THE INVENTION

The high-pressure reservoirs and cylinders for transportation/preservation/distribution of compressed gases from gas fields to consumers, are required to the protected from the atmospheric changes since body of the reservoirs if subjected to atmospheric changes, corrodes the outer layer and may cause accidents. Therefore to prevent the effect of atmosphere, the reservoirs/cylinders are kept inside containers, the containers are of many shapes as per the requirement or as per the shape of the cylinders. They can be dome shaped, spherical, cylindrical, and cubical or any other figures as desired or needs. For different operations of the cylinders the cylinders are joined with different type of pipefittings, which comes out of the container via one or many openings in the container. These containers are so made such that they can withstand the atmospheric changes. They are therefore kept in the open.

Since the containers are having one or many openings and are also kept in the open, the containers are utilized by pests, rodents, wasps, snakes, small animals or insects etc for their home. The rain, snow, hails, moisture etc can also pass through the openings. Therefore it is seen that the sole purpose of the containers are not being fulfilled.

According to the present invention there is provided a solution to the aforesaid problem by introducing a shield to the openings/windows. The shield is acting as a closing means for the opening/window and can be opened and closed whenever needed by the operator/user.

As shown in FIG. 1 the container (10) has an opening (20) that allows unwanted pests to dwell inside.

FIG. 2 shows a shield (30) to cover opening (20) of container (10). The shape and size of the shield (30) is made respectively to the opening (20) of the container (10). The material of the shield (30) is so selected which is a non-corrosive material, which is resistant to the atmosphere. The material of the shield (30) can be, but is not limited to, firs resistant. The material can be any lighter metal like steel, aluminum, brass etc. The non-metals like plastics, polymers etc can also be used which fulfills the above-said requirements.

The shield (30) has a sliding channel (40) (as shown in FIG. 3) to allow the shield (30) to sliding in and out of opening (20). The sliding channel (40) is U-shaped and extends ¾ of the way around the shield (10). The width of the sliding channel (40) is slightly greater than the width of the walls (25) of the opening (20) which is just enough for the free movement of the shield (30) in and out of opening (20).

FIG. 4 shows a view of the shield (30) from the bottom. FIG. 4 give a closer look at the sliding channel (40) and the walls (25) of the opening (20) fitting inside the U-shaped sliding channel (40). The walls (25) of the opening (20) fit in between the walls (45) of the sliding channel (40) to insure a clean fit of the shield (30) into the opening (20).

In an alternate embodiment shown in FIG. 5 the sliding channels (50) are separate from the shield (30) and can be welded to the frame of the opening (20). Care must be taken in welding so that the sliding channels (50) are perpendicular to the base and also the distance between the two channels is made such that it can accommodate the shield (30) through it. The shield (30) can move freely inside the channels.

In another embodiment of the present invention the shield (30) are so designed so that they have space for accommodating the pipe assembly (15) through them of as shown in FIG. 1. The space of accommodation can vary with respect to the area of the fittings.

In another embodiment of the present invention there is provided a conventional mechanism of locking means for security reasons. The lock can be a conventional lock wherein the lever for locking can be made attached to the body of the container (10). The conventional lock can be located on the shield (30) and a loop or hook or any conventional lock receiver can be located on the container (10) itself. The locking means can only be used if required by the operator/owner/user.

In yet another embodiment of the present invention there is provided an electric motor and a pulley arrangement for automatic opening and closing of the shield. The electric motor is attached on the top of the window connected with a pulley. The pulley is connected with a thread and further connected with the shield by means of a stud.
